Abstract

ÖzBu araştırma ıslah çalışmaları sonucu geliştirilen ileri kademe bazı arpa genotiplerinde tane verimi ve bazı agronomik karakterlerinin belirlenmesi amacıyla yürütülmüştür. Araştırma 2008Araştırma -2009 Investigation of Grain Yield and Agronomic Characters of the Some Barley (Hordeum vulgare L.) Genotypes in Trace Region AbstractThis research was carried out to determination yield and some agronomic traits of the cultivar and advanced lines developed by breeding works. Experiment was set up in 2008-2009 growing season in Edirne and Tekirdağ locations with 25 genotypes in randomized completely blocks design with four replications. Grain yield, plant height, lodging resistance, date of heading and maturity, resistance to powdery mildew and net blotch, 1000 kernel weights, test weight and protein ratio and relationship among these characters were investigated. The results showed that there were significant difference among the genotypes than grain yield and some other investigated characters. Mean grain yield of the genotypes was 524.1 kg/da, and the highest grain yield with 619.5 kg/da was determined in Martı cultivar. Mean yield was 488.3 kg/da and 560.0 kg/da in Edirne and Tekirdağ locations respectively. Plant height ranged between 89.5 cm and 108.5 cm. In Trakya region mainly widely disease is net blotch (Drechslera teres f. teres) and it was determined that almost all genotypes were medium susceptible to net blotch. The highest 1000 kernel wight was determined in TEA1619-20 and test weight in TEA1619-17 lines. According to protein ratio there was significant differences among genotypes and highest protein was determined with 12.5% in Lord cultivar. The highest grain yield was determined in genotypes with early maturating and tall plant height. Identifying positive relationship between lodging resistance and plant height (r=0.871**) it was showed that this character can be used for lodging resistance. Martı, Hasat, TEA1619-17 and TEA1619-20 had most prominent genotypes based on yield and some other investigated characters.

Investigation for Grain Yield and Quality Characteristics of Some Barley (Hordeum vulgare L.) Cultivars in Diyarbakır Conditions

“…Arpada bitki boyu, yatmaya dayanıklılık, verim ve verim bileşenleri ile kalite üzerinde etkileri bulunan morfolojik bir karakterdir. Tane veriminde ciddi kayıplara sebep olan yatmanın etkisini en aza indirebilmek amacıyla kısa boylu ve sağlam sap yapısına sahip çeşitlerin ıslahı için son yıllarda önemli çalışmalar yürütülmektedir [9]. Islah çalışmalarıyla kısa boylu çeşitler geliştirilmiş olmasına rağmen ülkemiz gibi hayvan yemi açığı olan ülkelerde saman önemli bir katma değere sahip olduğu için genelde geliştirilen çeşitlerde 80-100 cm bitki boyu istenmektedir.…”

Investigating of Some Agricultural and Quality Traits of Advanced Barley (Hordeum vulgare L.) Lines

“…Again, in many studies conducted under rainfed conditions, it was reported that the average PC was determined higher than this study with 12.4% (Doğan et al, 2014;Aydoğan et al, 2016;Sönmez et al, 2020). Many researchers have reported that the amount of PC in the grain may vary according to genotype, environment, and agricultural applications (Fox, 2003;Doğan et al, 2014;Öztürk et al, 2016;Kızılgeçi et al, 2019). PC in malting barley is expected to be between 9 -11.5% (Elgün and Certel, 1987).…”
